Be it known that itmmnrr A. HAMBUR- row, a citizen of the United Statesof America, residing at Connellys Springs, in

the county of Burke and titateof North or after the use of the same hasinvolved a considerable wear necessitating repair or renewal,

llt further object of the invention to provide a'device for the purposeindicated which is capable ofadjustment from time to time as the wear onthe parts proceeds without necessitating the dismounting of the axles orthe dropping of the wheels as is necesit it sary in connection with themeans heretofore used for a similar purpose.

With these and analogous objects in view the invention consists in aconstruction, combination and relation oi parts of which preferredembodiments are illustrated in the accompanying drawings, it beingunderstood that changes in form, proportions and details may be resortedto within the scope or theappended claim without departing fro theprinciples involved. i in the drawings:

Figure 1 is a face view of a journal bearinp adapted for car wheelaxles, the same beconstructed in accordance with the invention.

li igure is a plan view of the bearing boir liigures 3 and d arerespectively side and plan views of the brass spreading wedge Figure 5is a detail view of one of the brasses or brass members.

Figures 6 and 'i' are respectively side and plan views of one of thebrass members.

Figure 8 is a perspective view oi the same.

Figure 9 is a perspective view of one of the side or brass contractingwedges.

itigures 10 and 11 are respectively see-- tional and partial side viewsoi? the wedge shown in it Figure 12 is a face view of a slightlymodified :torm of bearing box and brass ad- }usting attachmentillustrating a construction which is common with relatively smallbearings.

.lz igure 18 isa sectional view taken on the plane indicated by the line13-13 of Fig; ure 12. a

Figure 14: is a plan view of the bearing illustrated in Figure 12.

lligures 15 and 16 are perspective views respectively of the side orbrass contracting wedges such asare employed preferably in connectionwith the construction of bearing illustrated in F igure 1?.

The bearing block or bOX 10 in the form 01 the device as illustrated inFigures 1 to 11 inclusive, is of the ordinary construction as far asexterior form or outline is concerned, the seat 11 for the brass represented by the members 12 and 13 being modified only to the extent ofproviding lateral recesses id for the reception. wedges 15 hereinreferred to as side or brass con tracting wedges and being taperedtoward their lower edges with bevelled inner surfaces 16 co-aeting withbevelled side. surfaces 17 of the brass members so that by iorcing theside wedges downward by means of the threaded stems or bolts 18 thebrass may be contracted or the members thereof may be moved toward eachother to contract the bearing SuI'iELCGS represented by the. innor sidesof the brass members. At the lowerends oi the recess i l there areformed pockets or extensions 19 for the reception of the lower reducededges of the side wedges to thus permit of a suiliciently extensiveadjustment of the wedges to eiiect the desired object; At their lowerextremities the brass members are outwardly and downwardly bevelled asshown at 20 to rest upon similarly inclined ledges 21 adjacent to theextensions or pockets 19, so that the tendency of the brass members isto move or settle outward or from each other by reason of the jarring ofthe structure, rather than to move inwardly or in the opposite directionand thus involve an excessive amount of friction upon the surface of theaxle or other journal which may be mount ed therein.

Between the upper extremities of the brass members there is interposedthe brass spreadingor expanding wedge 22 having its stem 23 entendedthrough an opening; in

lllltl a plate 24; bolted-or otherwise secured as at 25 to the face ofthe bearing block '01;

box, and obviously by loosening the nut 26 with \(l'llClLtllG stem 23 1shttQClthQlJl'ilSS mei'nbers may be permitted to move inward by thedownward adjustment o'l the side wedges 15.

The bolts 18 by which the movements. of

the side wedges are controlled are preferably headed as at 27 to fitinT-shaped seats 28 formed in thewedgesl5 'neai theirupper edges,saidheaded ends of thebolts being 7 insertible laterally into the seats andconstituting a swivel connection between the boltsand wedges, the formerbeing threaded to engage threadedopenings-tormed in the bearing box orblock so that by turning the bolts for: which purposethe upper endsthereof are provided witlr'wrench seatsSO, the side wedges may be"adjusted to secure a sufiiciently snug-fit 0f the brass members to I theaxle r or ournal mount ed there1n.-- The-uppei' edgeor" the bearingboxor block s hollowed out as'lndicated at3l to-forma grease well throughwhich the bolts 18 extend-, and-fitte'd upon the bolts and in contactwith the fioor of I this welt are jam nuts-'32 )which' serve to'loolcthe -bolts -and therefore the side wedgesun ad merely by loosening thewedge22 and tore- I in g the gside wedges downwardly by: turn ingthe{bolts 30 after loosening the j am nuts With certain ofthe' smallertypes of hear ing boxes or--blocks 33 as indicated in the form offthe]device shownin Figures 12 and 16 inclusive, it is impossible orimpractical to employ theuprightbolts for securing the Vdesiredad-justment of the side wedgeswhich are used to contract thebrass and therefore there is employed as indicaled in the drawings, inaddition to the lntBlPUrKd or sprernh ing wedge El i, a sectional. sideor contract ing wedge consisting of the brass cinfaging element 2}?) andthe operating clement 36, both of whirh are wedge-shaped and with thelatter provided with a stem 37 extending through the bracket or faceplate 2*; and fitted with an adjusting nut 3f). .Hler the loosening ofthe spreading wedge Illthe nuts 39 ,controlling the positions of theoperating wedge elements 36 may be :HljHSU-"l to secure the dmvnwardmoyen'ient of the brass contracting elements and thus aw complish thesame purpose as indicated with reference to the form of the inventionillustrated in l ignres 1 to 'l'l inclusive.

\Vhat is claimed is:

The combination of a bearin hox hariu itsbress receiving seat providedwith l1l1- eral recesses. a divided brass having its members arranged insaid seat and provided with downwardly and outwardly bevelled sidesurfaces terminating in outwardly bevelled bearing ends, hearing ledgesbeing PIOVldGd at the sides oi the box for the reception of saidbevelled extremities of the brass members, a brass spreading wedgeinterposed between the upper ends of the brass members, means foradjusting said spreading wedge, side or brass contracting wedgesdisposed in said recesses in engagementrwith the side bevelled surlaresoi the brass members, and means for adjusting said side wedges, therecess in which said side wedges are mounted being downwardly extendedbelow said bearingledges to term pockets "for the reception of thereduced edges of the side wedges.

In testimony whereof he afiixes his signature.
